A 50-year-old con artist has admitted to duping three Queens women out of nearly $5,000 through a phony “blessing” scam, officials said.

Queens District Attorney Richard A. Brown said Fengluan Qin confessed Thursday to using an ancient con game to take jewelry and large sums of cash from three unsuspecting Flushing women, between 52 and 72 years old.

Qin convinced the victims to place their cash and valuables into a bag for a “blessing ritual” that would cure their families of sickness and bad luck, before swapping the bags and stealing the goods, Brown said.

Victims of the hoax have lost $1.3 million within the last year to different crews moving throughout the city, according to Inspector Brian Maguire, commanding officer of the 109th Precinct.

Out of about 50 cases citywide, more than $500,000 has been pilfered from victims in the 109th precinct alone, Maguire said.

According to Brown, the scam that targets mostly elderly immigrant women is prevalent in Asian communities nationwide.

“People should be aware that this is just one of many confidence tricks used by individuals to swindle money from vulnerable people and should not fall victim to it,” Brown said.

The district attorney’s office said Qin, a Chinese national with an expired visa, was believed to be living in Flushing, though she did not provide an address to authorities.

She pleaded guilty to grand larceny charges on December 5, Brown said. She is expected to be sentenced to one to three years in prison on December 18.

As part of the plea deal, Qin must also forfeit $4,765 in restitution and sign a confession of judgment for another $10,000.

Police are urging families to spread word of the scam to older relatives and friends.

Cops said victims, if approached, should agree with the tricksters on a meeting spot and then go home and call 9-1-1.
